    摘要: PROBLEM TO BE SOLVED: To provide alternative sulfur based corrosion inhibitors overcoming sensitivity to chlorine as the fault of tolyltriaozole widely used as corrosion inhibitors to yellow metal. SOLUTION: The fact that dithiocarbamate compounds are sufficiently strongly effective as sulfur based corrosion inhibitors to be bonded with metals, particularly with copper since they form protective barriers or protective films has been found. Further, the fact that, in the compounds as inhibitors, at the time when the substitutional groups of the aliphatic or aromatic series are changed, remarkably influence is exerted on the performance of being filmed has been found. By optimizing the balance between the hydrophobicity and cubic properties of the shields in the substitutional groups, the improved corrosion inhibitors can be provided. COPYRIGHT: (C)2006,JPO&NCIPI
